Definitions

  • Movement is a critical activity and state for all organisms, including man. Movement may be considered as being of two types: complete translation or translocation of an organism from one location to another - examples here being walking, running, somersaulting, falling or the like; or alternatively movement may be considered the displacement, bending, angulation, rotation, or other positional alteration of the organism or components of the organism - e.g. a limb, the head and neck, the upper torso, the trunk without significant translocation of the overall organism as in going from location A to location B. Although movement and flexibility of particular j oints may be quantified, there is no measurement or quantification of overall movement and flexibility of an organism.
  • an organism such as a human or animal has the ability to move all or a portion of its body, soma or corpus. Movement of the body, body part or appendage may be either active - e.g. as in bending over, lifting an arm, tilting the head and the like, actuated via internal neural commands and intention, or passive. For passive movement another individual, device or system moves the appendage such as in someone moving a test subjects arm to determine what has been colloquially referred to as range of motion, but is more accurately a "range of flexibility.” Within both of these forms or movement there is a defined maximum range of movement that is three-dimensional. If one were to trace the outer perimeter and capture and visualize the entire "volume" of space covered by this movement this would be define, both quantitatively and qualitatively, the "motion or movement envelope " - i.e. for active, volitional or stimulated movement or the
  • the "flexibility envelope” is a region that may be equal to, larger or smaller than the motion or movement envelope.
  • the size, volume or extent of the flexibility envelope is governed by the limberness, elasticity, laxity and otherwise overall flexible nature of the body region, appendage or limb being tested.
  • the degree of flexibility of a given organism or test subject varies depending upon how much activity the organism regularly performs, the degree of intactness, i.e. freedom from injury, and on the age or state of health of the organism.
  • the extent of the flexibility envelope is also governed by whether the activity performed to define the envelope is active and volitional or passive by a third party or system.
  • the motion and flexibility envelope may overlap in full or in part.
  • an individual may only be able to move a limb actively to a defined limit or cover a defined volume of space.
  • the range of motion may be greater, largely governed by the
  • both the motion and/or flexibility envelopes may be defined and their degree of overlap or non-overlap determined.
  • motion and flexibility are typically measured individually as a single parameter for a single appendage.
  • a person has an injury that affects an elbow joint, such as a broken arm that requires immobilization of the elbow joint to allow the bone to heal, this immobilization typically results in reduced flexibility of the elbow joint.
  • Rehabilitation of the joint typically requires physiotherapy to improve range of motion and flexibility of the elbow joint, where motion and/or flexibility is measured in angular degrees of movement of the forearm relative to the upper arm.
  • a method determines an overall motion and/or flexibility envelope for an individual. Movement and position data of the individual is captured and processed to generate an overall motion and/or flexibility envelope for the individual defining overall motion and/or flexibility of the individual.

  • the system includes a flexibility server having memory and a processor and adapted to receive movement and position data of the individual, a motion and/or flexibility analyzer, implemented as machine readable instructions stored in the memory and executed by the digital processor, capable of processing the movement and position data to generate an overall motion and/or flexibility envelope for the individual defining overall motion and/or flexibility of the individual.
  • a system determines an overall motion envelope for an individual.
  • the system includes means for capturing motion of the individual, means for recording and analyzing said motion data, means for storing raw and processed information, means for converting the motion data into a flexibility envelope, means for displaying the flexibility envelope, and means for comparing the flexibility envelope at differing time points and under differing conditions.
  • a method determines an overall motion and/or flexibility envelope for an individual. Movement and position data from at least one sensor or motion detection means configured with the individual is captured and analyzed to generate the overall motion and/or flexibility envelope for the individual. A display from the overall motion and/or flexibility envelope is generated to show motion and/or flexibility of the individual.
  • a software product has instructions, stored on non-transitory computer-readable media, wherein the instructions, when executed by a computer, perform steps for determining an overall motion and/or flexibility envelope for an individual.
  • the software product includes instructions for capturing movement data, instructions for analyzing movement data, instructions for converting data into a graphical representation of movement in either 1,2,3 or 4D, and instructions for comparing movement of any aspect of full or partial flexibility envelope to either another point of time of the envelope of the same individual or of a database of performance.

  • An organism's current overall motion and/or flexibility envelope is evaluated against a recorded overall motion and/or flexibility envelope for that individual organism or against a large database (of continuously updated - i.e. akin to machine learning) to determine trends in motion and/or flexibility over time.
  • This overall motion and/or flexibility envelope defines motion and/or flexibility of the organism, where individual portions of the overall motion and/or flexibility envelope may be measured and defined in many various ways, such as x-y-z plane movements, pitch-roll-yaw movements, polar or circular coordinates, and so on.

  • the individual motion and/or flexibility measurements are combined to form the overall motion and/or flexibility envelope that is stored digitally and may be processed, evaluated, and presented in many recognizable and usable forms to indicate overall motion and/or flexibility of the organism or of components of the organism - e.g., a given appendage such as an arm.
  • a human body has two-hundred and thirty movable j oints, each with a certain range of motion based upon the type of joint.
  • the human body has three types of joint: (a) fibrous joints that are held together by strong connective tissue with only a slight capacity to stretch and have very little movement between the joined bones, providing great stability; (b) cartilaginous joints that allow for slight movement and occur where bone ends are covered by a somewhat flexible, compressible connective tissue called cartilage; and (c) synovial joints that consist of a capsule of connective tissue that encloses a space or cavity between the bones to allow the greatest degree of movement.
  • Measuring a range of motion for a specific joint on a body does not provide a complete indication of overall motion and/or flexibility of that body. Certain embodiments disclosed herein provide quantification of overall motion and/or flexibility and an overall motion and/or flexibility envelope for any organism.
  • j oints which may be conceptualized as hinges, defined body elements - e.g. appendages (arms/legs), the head and neck and the trunk, the upper torso and the lower torso may be envisioned as "flex elements.”
  • a flex element of a corpus is herein defined as any element of the corpus of an organism - either contiguous or discontinuous (not immediately adjacent), that regardless of physical proximity are considered as a functional group.

  • FIG. 1 is a 2-D high level visualization of an overall motion and/or flexibility envelope 150 for an individual human body 102 (hereinafter individual 102). It should be understood that the full or max flex envelope is actually a 3-D structure at a given moment of time and a 4D structure taking time into account.
  • the overall motion and/or flexibility envelope 150 encompasses and defines all possible non- traumatic/acci dental movements of individual 102, whether active (i.e. performed by the test subject themselves_ or passive (i.e., performed by an exogenous testing individual, device or system).
  • overall motion and/or flexibility envelope 150 expands to encompass the demonstrated motion and/or flexibility of individual to perform those activities.
  • Overall motion and/or flexibility envelope 150 changes for individual 102, for example as individual 102 ages from birth through childhood, overall motion and/or flexibility envelope 150 expands to encompass the increased motion and/or flexibility of the child as he/she becomes mobile. Where individual 102 participates in advanced training (e.g., Yoga, sporting activities, and so on), overall motion and/or flexibility envelope 150 increases as a result of the body 103 becoming more flexible and limber through the training. As individual 102 ages through senior years towards the end of his/her life cycle, overall motion and/or flexibility envelope 150 decreases as the body 103 loses flexibility through decline and decay. Where individual 102 changes body rhythms, such as patterns in regular activity, overall motion and/or flexibility envelope 150 also changes.
  • advanced training e.g., Yoga, sporting activities, and so on
  • overall motion and/or flexibility envelope 150 increases as a result of the body 103 becoming more flexible and limber through the training.
  • overall motion and/or flexibility envelope 150 decreases as the body 103 loses flexibility through decline and decay.
  • overall motion and/or flexibility envelope 150 encompasses the resulting flexibility achieved by such exercise. However, if individual 102 then stops exercising regularly, overall motion and/or flexibility envelope 150 reduces as individual 102 loses flexibility due to reduced activity. In another example, individual 102 suffers an injury and overall motion and/or flexibility envelope 150 is reduced. As individual 102 recovers from the injury, and possibly uses appropriate rehabilitation, overall motion and/or flexibility envelope 150 increases again. By comparing a current overall motion and/or flexibility envelope 150 for individual 102 with a previously recorded overall motion and/or flexibility envelope 150, changes in overall motion and/or flexibility can be determined and visualized, thereby allowing individual 102 (or a medical practitioner) to better understand the effects of rehabilitation.
  • Overall motion and/or flexibility envelope 150 is also affected in the short term. For example, where individual 102 has been confined to an aircraft seat as a passenger, upon disembarking from the aircraft, overall motion and/or flexibility envelope 150 of individual 102 is temporarily reduced. Similarly, after participating in a sporting activity, overall motion and/or flexibility envelope 150 of individual 102 may be temporarily extended because of warm and stretched muscles. Thus, overall motion and/or flexibility envelope 150 is continually changing.
  • FIG. 2A shows example motion and/or flexibility components that form overall motion and/or flexibility envelope 150 of individual 102.
  • Individual 102 has two- hundred and thirty movable joints.
  • Overall motion and/or flexibility envelope 150 is based upon motion and/or flexibility of at least some of these j oints.
  • Overall motion and/or flexibility envelope 150 may be based upon motion and/or flexibility of all of these j oints; however, certain ranges of motion, and this flexibility, may be difficult to measure. Therefore, in embodiments, motion and flexibility of certain j oints (e.g., the fibrous joint that limits movement between the tibia and fibula bones of the lower leg) may be derived from indirect measurement.
  • certain j oints e.g., the fibrous joint that limits movement between the tibia and fibula bones of the lower leg
  • FIG. 2A shows regional grouping of individual motion and/or flexibility components (i.e., inputs 202-214) to form an upper torso 201 flexibility element.
  • components 216, 220, and 226 may be regionally grouped as a left leg 227 flexibility element. Other regions may be similarly grouped, where groups may be nested and overlapped.
  • FIG. 2B shows example grouping of external and internal components to form an internal/external group 261. That is, external components of a left arm 251 flexibility element may be grouped with internal components such as aorta flexibility 252 and heart flexibility 254 to form internal/external group 261.
  • internal components such as aorta flexibility 252 and heart flexibility 254
  • one or more sensors may be implemented within the body of individual 102 and communicatively connected with a relay device (e.g., relay device 304 of FIG. 3) that collects and relays data wirelessly from these internal sensors.

  • overall motion and/or flexibility envelope 150 is illustratively shown derived from fourteen different motion and/or flexibility inputs 200: left wrist motion and/or flexibility 202, right wrist motion and/or flexibility 204, left elbow motion and/or flexibility 206, right elbow motion and/or flexibility 208, neck motion and/or flexibility 210, left shoulder motion and/or flexibility 212, right shoulder motion and/or flexibility 214, left hip motion and/or flexibility 216, right hip motion and/or flexibility 218, left knee motion and/or flexibility 220, right knee motion and/or flexibility 222, back motion and/or flexibility 224, left ankle motion and/or flexibility 226, and right ankle motion and/or flexibility 228.
  • FIG. 2 does not show all possible motion and/or flexibility inputs 200.
  • the human body has two-hundred and thirty movable joints; thus, overall motion and/or flexibility envelope 150 may be derived from many other motion and/or flexibility inputs without departing from the scope hereof.
  • Overall motion and/or flexibility envelope 150 may be defined, in part, as motion in different planes of appendages of individual 102.
  • Neck motion and/or flexibility 210 may be derived from multiple measurements of motion and/or flexibility. For example, individual 102 may be able to move his/her head backwards and forwards over a certain range in a first plane, sideways over a certain range in a second plane, and rotate his/her head through a certain range in a third plane. These ranges and planes combine to form neck motion and/or flexibility 210.
  • this overall motion and/or flexibility envelope is complex. For example, measurement of movement of a single joint is only part of the overall motion and/or flexibility envelope. Thus, in part, the overall motion and/or flexibility envelope is a measurement of all motion and/or flexibility of the body.
  • Capabilities and actions of individual 102 throughout the day depend upon the individual's motion capacity and flexibility.
  • overall motion and/or flexibility envelope 150 provides a signature, or status, of well- being of individual 102 at a particular moment.
  • overall motion and/or flexibility envelope 150 is more than physical motion and/or flexibility. It may also include emotional states that are based upon, or may influence, the physical mobility and flexibility of the individual. For example, where the individual is stressed, his/her muscles may be tense, resulting in less motion and/or flexibility. Thus, overall motion and/or flexibility envelope 150 may include other health information that relates to, or influences, the motion and/or flexibility of the individual. That is, overall motion and/or flexibility envelope 150 is derived based upon physical motion of one or more body components, appendage or flexibility elements (i.e., groups of components). The detected physical motion is governed by the material properties of the constituent component structures - i.e. muscle, ligaments, tendons, presence of edema, blood flow, venous and lymphatic drainage and the like. In addition to physical elements, hormonal, neural and emotional (e.g. stress, fear) factors and states also modulate this motion and degree of flexibility.

  • Overall motion and/or flexibility envelope 150 is multi-dimensional and encompasses the entire body of individual 102.
  • overall motion and/or flexibility envelope 150 extends far beyond simple j oint range of motion measurements (e.g., movement of the elbow joint of one arm) that have a linear range - say 0-100, where 100 represents full range of motion.
  • Simple measurement of motion range also fails to take into account the three dimensional nature of many j oint motions.
  • an individual has a broken arm that is set in a plaster cast. A simple evaluation of the individual's arm would indicate no range of motion or the lack of flexibility. However, that simple assessment provides no indication of how the individual is coping with that injury.
  • Motion and/or flexibility of individual 102 may be determined by detecting movement of one or more body parts relative to one or more other body parts.
  • left elbow motion and/or flexibility may be determined by detecting movement of a left forearm relative to a left upper arm.
  • Such movement may be determined by one of three ways: implantable sensors that measure movement from within the body, wearable sensors that attach to the body to determine movement, and off the body sensing, where body movements is determined using external apparatus, such as in a wired room that utilizes one or more of machines and cameras to detect body movement.
  • sensors may be implanted on, in or near body internal elements, organs or organ components. These sensors allow motion and flexibility determination of a defined “flex element.” For example, if one were to track the left upper extremity and the heart and lungs - these could be defined as a “flex element” or group.

  • sensor data 306 includes three dimensional position and/or movement information for each sensor 302.
  • Flexibility analyzer 316 manipulates body model 318 based upon the received sensor data 306, such that body model 318 simulates movement of individual 102. For example, as shown in FIG. 3, as individual 102 bends at the waist, to the position shown as individual 102"', body model 318 is manipulated to follow the movement indicated within sensor data 306 for sensors 302(1) and 302(2). It is noted that other parts of body model 318 also move to achieve the defined movement. For example, the shoulders, arms, and head have also moved relative to the right thigh (sensor 302(2)), although they remain positioned relatively stationary relative to the lower back (sensor 302(1)). Thus, by correctly modelling movements sensed by sensors 302(1) and (2), movement of other body parts and joints may be derived, even when sensors are not configured to directly measure those movements.
  • Flexibility analyzer 316 then reads flexibility ranges (including derived flexibility) of the right hip joint, from body model 318 and inputs right-hip flexibility 218 to overall motion and/or flexibility envelope 150. Since body model 318 also determines flexibility of other joints, even when not directly measured, even without full sensor instrumentation of individual 102, body model 318 may derive movement and thus flexibility ranges of other j oints.
